A couple wanted to install a square mirror that has:
Area of the mirror = 500 square inches.
x = nearest tenth of an inch , length of wood needed
s = sides of square
Area = s2
500 (area) = s2 | √
x = √500
=> √ 5 x 100
=> √ 5 x √100
=> 10 √ 5
=> approximately 22.4
Since we’re looking for the nearest tenth of decimal place value, the answer is
approximately 22.4
